AttributeError 'Button' object has no attribute scrlFBtn. What is the problem? I'm trying to make it so that when you clicked, the screen was cleared (Widget was deleted). Рelp me please =)

Your code has several errors and bad programming practices:

• if you declare variables that are inside a class and outside any method of the class will be class variables and not attributes of the class, so it is not a good practice to do so if you want to use later self, all that code must be within a method of a class.

• on_someproperty wait as parameter a function that receives parameters, in your case sas() does not receive them so the solution is to use a lambda method.
